Surah Al-Isra' (The Night Journey), Verse 95

قُلْ لَّوْ كَانَ فِی الْاَرْضِ مَلٰٓىِٕكَةٌ یَّمْشُوْنَ مُطْمَىِٕنِّیْنَ لَنَزَّلْنَا عَلَیْهِمْ مِّنَ السَّمَآءِ مَلَكًا رَّسُوْلًا ۟

Qul law kaana fil ardi malaaa 'ikatuny yamshoona mutma'in neena lanazzalnaa 'alaihim minas samaaa'i malakar Rasoolaa

“Say, "If there were settled, on earth, angels walking about in peace and quiet, We should certainly have sent them down from the heavens an angel for a messenger."”
